Brewster Angle Experiment
OBJECTIVES
Measurement of Brewster’s angle for a given dielectric dispersive medium.
PRINCIPLE
When un-polarized light is incident on the surface of a dielectric (such as a glass), at a certain angle of incidence the reflected light is completely plane-polarized. This phenomenon was discovered by Sir David Brewster and, thus, the specific angle is called Brewster’s angle or polarization angle. Also, from the experiment, it can be confirmed that the reflected ray and the refracted ray are 90° apart when the incident angle is set at Brewster’s angle.
KEY FEATURES
- Rotating Table: A simple, smooth, and compact rotating table. The rotating table used is extremely smooth to operate. It is a single assembly that holds a glass sample, analyzer, and light sensor, thus minimizing the size of the whole equipment. Smooth rotation makes measurement continuous and accurate.
- Light Sensor: This enables the measurement of light intensity at various angles of reflection. The meter reads with a precision of 1 lux. The Lux meter helps obtain a continuous smooth curve of angle vs intensity and determines the Brewster angle much more accurately than the manual method.

Mechanics
Apparatus for Bernoulli’s Principle
Principle:
The Bernoulli’s Experiment utilizes a streamlined channel equipped with a pressure sensor strategically has ability to place at various cross-sections of the flowing air. By measuring dynamic and static pressures at these points under controlled flow conditions, the system verifies Bernoulli’s equation.
Objective:
- To experimentally confirm the validity of this equation, which describes the conservation of energy in fluid flow.
- To measures static and dynamic pressure at different points within a flowing fluid, alongside flow rate and temperature
- To analyses the relationship by controlling flow rate and monitoring pressure changes, between pressure, velocity, and elevation, as defined by Bernoulli’s equation.
Key Features:
- Streamlined Design and Wireless Technology: The apparatus features a compact and easy-to-use design with strategically placed pressure sensors. Wireless sensors eliminate the need for cumbersome cables, enhancing portability and ease of use.
- Real-time Data Acquisition and Analysis: Data from the wireless sensors is transmitted directly to a tablet, allowing for convenient graph plotting and real-time analysis of pressure changes. This simplifies data collection and visualization, streamlining the verification process.
- Cost-Effective and Transparent Design: Compared to alternative systems, the Supertek apparatus offers a more affordable solution for verifying Bernoulli’s principle. Additionally, its transparent acrylic cover allows for clear visualization of the air flow within the channel, enhancing the learning experience.
